It is indeed Chartreuse. There is also a "must-see" that presents "a magnificent view" of Chartreuse when it is actually Belledonne!!

From this cross there is a splendid view of the Chartreuse massif, the Grésivaudan valley towards Grenoble and Chambéry, the Belledonne massif and, as an added bonus, there are orientation tables. Super 👌!

The approach from the south is very nice, the descent to the north via the forest road is not allowed, but with great caution and pushing in tunnels possible
